14 Claims.

This invention relates to an improved multicolor pencil assembly in which the number of components is reduced to a minimum, thereby insuring their expeditious handling both as respects collocation and dismantlement, as well as simultaneously providing for production of the complete unit at relatively low cost.

To the accomplishment of the recited objects, and others co-ordinate therewith, the preferred embodiment of the invention resides in the construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings and embraced within the scope of the appended claims.

Referring to the accompanying drawings:

Fig. l is a side elevation of a pencil embodying this invention.

Fig. 2 is a side elevation of the pencil casing and the channel guides element removed therefrom and in position for insertion therein.

Fig. 3 is a side elevation of one of the lead carriers disposed towards the left. Fig. 3 is a front elevation of the lead carrier.

Fig. 3 is a view similar to Fig. 3, only the carrier is disposed towards the right.

Fig. 4 illustrates in side elevation various components of the pencil.

Fig. 5 is a side elevation of one of the constituent plates of the channel guides.

' Fig. 5* is a like view of the companion plate.

Fig. 6 is a transverse section along lines 6-6 of Fig. 1 showing the channel guides per se.

Fig. 7 is a vertical longitudinal section of the upper portion of the pencil assembly exhibiting the position of the locking sleeve just prior to its being thrust into engagement with the stud, and

Fig. 8 is a similar view illustrating the position of the locking sleeve after it has been forced home.

Referring more particularly to the drawings, 5 designates a casing provided with two or more longitudinal slots 6, at the outer end of which the metal, or other material of which the casing is formed, is depressed, as at 1. On one side of the vertical median line of the casing and adjacent the top thereof is an opening 8; on the other side is a vertical slit 9 which terminates a short distance below the top edge of the casing.

Noting especially Figs. 5 and 6, it will be observed that the channel guides, which are designed for directing the movement of the lead carrying units, comprise a pair of oblong plates 1 Ill-l l, of substantially identical contour. Plate III has a medial longitudinal kerf l2 and a lateral flange I 3 at its upper left hand corner. And

plate II is devised with a medial kerf H, a flange l5, and a supplemental kerf I6 directly in the rear of said flange to allow of a certain degree of resiliency when pressure is brought to bear on the flange. In setting up the guides, the two plates are disposed at right angles to each other with kerfs l2-I4 in line; then they are forced over each other until the inner ends of the kerfs abut, with the result that a guide with four channels l1, l8, l9 and 20 is produced.

The next step in the assembly is to introduce the guide as a unit into casin 5, which is accomplished by compressing the flange l5 slightly so. that the outer edges of the four guides will accommodate themselve to the interior diameter of said casing, then constraining the guide downwardly, bringing flange l3 into registration with slit 9, and continuing the downward pressure until flange l3 reaches the bottom of slit 9this position being indicated by dotted lines in Fig. 2. In conjunction with this step, slit 9 predetermines centering of the guide plates with respect to slots 6 of the casing, and simultaneously precludes relative rotation of the guide unit and the casing.

Following, the lead carriers 2| (see Fig. 3) are inserted into the guides lll8l920, and with the thumb-pieces 22 of the carriers, partially protruding through the slots 6, the carriers may be shifted forwardly or backwardly, as desired. .In this connection, the depressed portion I at the outer end of each slot 6 eliminates the possibility of the front end of the thumb-piece becoming caught beneath the metal of the easing when the thumb-piece has been advanced to its forward position.

In assembling the upper extremity of the penoil, the tubular lead magazine or closur member 23 is disposed within the casing 5 and the opening 24 thereof made to coincide .with opening 8 of the casing. Then the clip-unit or sleeve 25, carrying the usual clip 26, and also having an opening 21, is telescoped over the corresponding extremity of the casing until the latter opening may be engaged at its extremity 30 and temporarily withdrawn from contact with the stud, thereby permitting dismantling of th various units.

The ingenious method of thus assembling the components of the pencil not only makes for celerity in production, but also for facility with which the components may be disassembled.

I claim:

1. A multi-color pencil, comprising in combination, a casing provided with longitudinal slots, channel guides provided with yieldable means engageable with the casing, and lead carriers nested in said guides and shiftable through said slots into operative and inoperative positions.

2. A multi-color pencil, comprising in combination, a casing provided with a slit at one extremity, channel guides within said casing and having a portion thereof engageable in the slit, and lead carriers operable in the guides.

3. A multi-color pencil, comprising in combination, a casing, channel guides in said casing, said guides having a compressible portion engageable with the inner wall of the casing, and

- lead carriers operable in the guides.

4. A multi-color pencil, comprising in combination, a casing provided with a slit at one extremity, channel guides within the casing, said guides having a flanged portion engageable in the slit and a compressible extremity engageable with the inner wall of the casing, and lead carriers operable in the guides.

5. A multi-color pencil, comprising in combination, a casing provided with long slots, channel guides within said casing including a pair of plates, each plate having a kerf extending part way of its median line, and the kerf of one plate adapted to interfit with the kerf of the other plate to present a composite structure having a cross sectional contour simulating a cross, and lead carriers operable in the guides.

6. A pencil, comprising in, combination, a casing having a longitudinal slot and a depressed portion at the forward terminal of the slot, a lead carrier, a thumb-piece mounted on said carrier and operable in said slot.

7. A multi-color pencil, comprising in combination, a cylindrical casing provided with longitudinal slots, substantially rectangular guides within said casing, said guides including a pair of separable crossing plates having interfitting axial slots extending respectively from the top and from the bottom thereof and presenting channels therebetween, means for centering the plates with respect to the slots, and lead carriers nested in said channels and shiftable through the slots into operative and inoperative positions.

8. A multi-color pencil, comprising in combination, a casing provided with longitudinal slots, spaced guide members within said casing, means for predetermining centering of the members with respect to the slots, and lead carriers nested between said members and shiftable through the slots into operative and inoperative positions.

9. A multi-color pencil, comprising in combination, a casing provided with longitudinal slots, spaced guide members within said casing, means serving the dual function of centering the members with respect to the slots and precluding rotation thereof relative the casing, and lead carriers nested between said members and shiftable through the slots into operative and inoperative positions.

10. A pencil comprising a casing, a closure member within the casing, a sleeve surrounding the upper extremity of the casing, each of the casing, the closure member, and the sleeve having a lateral opening, all of said openings being in registry, headed means inserted through said openings for holding the casing, closure member and sleeve together, and removable means for anchoring aid headed means in position.
